Consider the following initial rate data (at 297 k) for the decomposition of a substrate (substrate 1) which decomposes to product 1 and product 2: [substrate 1] (m) initial rate (m/s) 0.4 0.09136 0.8 0.36544 2 2.284 determine the half-life for the decomposition of substrate 1 when the initial concentration of the substrate is 2.46 m.
